This time we measured the sound pressure level and found out, that this PSU has a common fan speed regulation. The RPMs are tolerable up to 50-80% load. Beyond that point, this PSU is no more silent than competing solutions, but we should keep in mind that most GPUs are louder while gaming so the results are fine. Note the difference the power grid makes in terms of efficiency. 115VAC means higher current and more stress for all power supplies, while 230VAC shows a worse power factor at all loads. Nevertheless, 0.823-0.988 PFC is still good and most users will find 87% efficiency more than sufficient.
All the rails fall clearly within ATX specifications. They start slightly over the target voltage and end with results close to -2%. Since this PSU has four 12V outputs, we selected the worst rail for the tables (which is our standard procedure). +12V shows the best regulation, and will have no trouble with higher voltages. Both smaller rails have less than 30mV ripple and noise, while +12V reached 75mV.

another 'non profit' cause of the hour. wouldn't be surprised if this WWF and InWin have some family connection.i'd be more impressed if each $1 got split by the employees inhaling all those production fumes created during manufacturing of these things.

"However, the WWF is discredited as they are industry-related in some way. They got donations from the energy industry and tolerated genetically changed soy."Did you forget your journalistic integrity in your other pants or something?

(Not exactly.)I sold my integrity for an ecofriendly Porsche Cayenne Turbo !
Oh, I said the loud part soft and the soft part loud.

Is this an attempt at a joke?ggathagan - Thursday, June 7, 2012 - link
No, it IS a joke!Thank you, Martin.

More like a bad attempt at snark. Anandtech should stick to tech, which is what it does best; leave the political and scientific commentary to other sites like Ars.effingee - Wednesday, June 6, 2012 - link
Oh, wow! Tell me all about your Porche, but don't forget to throw in a random line about your opinion on collective bargaining for public service unions, too, so I'll know which Porsche to buy and who to vote for in my state primary election.If you're going to write a tech review, cool, write a tech review. If you're going to write a review of the World Wildlife Foundation, do it on your blog or something. Those two sentences about what you think about the WWF, factual or not, have no business in a review of a power supply. Let your readers think for themselves.

Actually, I think they do when the supply's big "feature" is that a portion of all sales go to the WWF.I've got no idea on how credible the WWF is(though they apparently funded the hiring of mercenaries to hunt poachers, which is awesome), but I really hate this sort of feel-good marketing.
At best it's a band-aid for the end user's conscience that lets them pretend they care without actually doing anything. More aggressive forms can come off as emotional blackmail(buy our stuff or children will starve in Africa!).
If they were really worried about the environment, they'd just say "In Win donates 10% of their net profit each year to the WWF" or some such.
And, you know, ship power supplies that are 80 Plus Platinum instead of 80 Plus Bronze.

Wrong WWF?jontech - Wednesday, June 6, 2012 - link
Or could have gone withMEAN.... WOOOO.... GREEN
O i digress
